CC has lowered my daily burn rate from 2070 to 2020; is it based on my input over months?

Does CC actually recalculate my burn rate based on how I'm taking in calories and losing weight over months, or do they just have a new formula? 

If you've lost weight, your burn calculator automatically adjusts your burn to your new weight.

Hope that helps!

As your weight decreases, so does your daily calorie needs. The less you weigh, the less you burn.  CC will take care of this part of the math throughout. I have watched my daily burn estimate decrease from over 3000 a day (including my logged work outs) to just under 2500 calories a day. Every time you enter a new weight CC makes the adjustment for you.  It's a good thing! It shows that you have made progress 

Increased muscle mass burns more calories per day, but CC uses an average estimate for this part of the equation.

Good luck!

Basically, as your body gets smaller, it needs less food to run, so your matabilism drops.  It means you're doing well, although it does make those last few pounds really anoying.

it is all computer generated based on what data you put in..I have been told my weight Goal will not be hit until July 09, I expect to hit it by June 09.  Am I right or the CC computer program? 

Maybe I did not put in enough info, maybe I missed some data..but based on what I put in that is what I get back.   It is only a guideline and great way to have additional data as you lose the weight.  But you must decide in the end what is best for you and what works for you.   Computer programs are great but they are not 100% all the time.

CC has recently changed its calculations from using the old Harris-Benedict Formula (1919) to the more recent Miffin-St Jeor (1990) formula. Everything will have been recalculated. The new formula is definitely lower.

You can check this by going to http://www.phord.com/cc/, which shows the results using both formulas.

There was an email update from CC regarding the change over recently. Unfortunately I can't find the appropriate link for that at the moment. In any case, it has been changed.

I've also seen my weightloss goal date decrease by a couple months. I love this system.
